This is one of my favorite recipes, and so easy to make! If you like it spicy, add the cayenne pepper and keep a few of the pepper seeds in. If not, throw out all the seeds and don't add the cayenne pepper.
1/2 bunch of cilantro
2 tomatillo peppers, husks removed
1 serrano pepper, seeds and veins removed
Juice from 1 lime
1 clove of garlic, peeled
1/2 tsp of cayenne pepper
1 pckt. of ranch salad dressing mix
1 cup of milk
1 cup of mayonnaise
Put all ingredients in a blender and blend well! That's it, so easy, so yummy!
